I see. It's just a simple abstraction for the Readers-Writers
problem.

I also found a stub in sysdes/generic for machine-lock.h. It defines
the atomic __spin_lock operations and there are non stub implementations
for severa arch's. It contains very few definitions. So I think I'll
add more definitions and use __spin_lock's throughout pthreads.
